Outcome

"Watchers on the castle walls saw distant blasts of flame and heard a shriek drown out the thunder. Prince Lucerys fell, broken, to be swallowed by the waves. With his death, the war of ravens came to an end and the war of fire and blood began."

The Dance

However, Aemond wanted blood. On his way back to Dragonstone, Lucerys was caught in a storm above the fortress, and his young dragonArrax could not take it. Aemond then rose to Lucerys' elevation on Vhagar, who was five times the size of Arrax. Vhagar bit into Arrax's neck so hard that she decapitated him. Arrax's lifeless body fell, with Lucerys on it, and he drowned in Shipbreaker Bay.

Aftermath

In the books

Lucerys flew to Storm's End, arriving before a gathering storm. He found PrinceAemond and his dragon Vhagar already present. Aemond tried to goad Lucerys into a fight, insulting him, calling him a Strong bastard, but Lucerys, sworn not to fight, refused him. He delivered his message to Lord Borros Baratheon, but was refused and told to leave.

Borros prevented Aemond from attacking his cousin in the castle, but did allow for the prince to follow him. Mounted on his dragon, Aemond caught up with Lucerys during a raging storm. The fight between the two dragons did not last long. Vhagar, being five times bigger, had the advantage, and Arrax fell broken. His head and neck washed ashore three days later, along with the corpse of Lucerys.
